Lower Mattagami, Kapuskasing, ON
This project retired the old 52-megawatt (MW) Smoky Falls Generating Station and constructed a new 271-MW station immediately adjacent to the existing plant.
3 other power generating stations were built along the Mattagami River:
In total, the project produces over 440 MW.
Hydro stations typically remain in service for 90 years or more. Hydro electricity is crucial to Ontario's electrical system because it provides renewable energy on demand, when it’s needed most.
